It’s often useful to make changes inside the current transaction, that would not be rolled-back if transaction is rolled-back. For example to do some logging.

This can be achieved by using global that is mapped to temporary database -- IRISTEMP. All globals that start with ^IRIS.Temp* are mapped to IRISTEMP by default. Problem with such approach is that IRISTEMP is cleaned on InterSystems IRIS restart, so this log is lost.

What else you can do is -- suspend transaction temporarily, do the logging, and then resume the same transaction.

Did you know that Caché (and now InterSystems IRIS) has available parser for ObjectScript ?

Well, technically, lexer. It hides under the name of %SyntaxColor class. This class provides API to the DLL used by Studio to do syntax highlighting. As a result if works only under Windows.

For example for Evgeny Shvarov, Comments tab shows 838, but there are no comments shown:

Dmitry Maslennikov, Comments tab shows 375, but no comments are shown:

https://community.intersystems.com/user/11906/comments

Interesting anecdote I want to share. Not 100% Caché related, but I hope it would be useful.

When CSP Gateway is configured on IIS, opening CSP Gateway Configuration page is prohibited by default -- as IIS blocks URLs with '/bin' in it.

In our documentation we advise to add <remove segment="bin" /> to applicationHost.config file. That is correct.

Recently I had problem when manual editing file Windows\System32\inetsrv\config\applicationHost.config has absolutely no effect on IIS.

Turned out (http://serverfault.com/a/599865) IIS was 64-bit and notepad++ that I used for editing was 32-bit.

In this article we are going to compare $Increment and $Sequence functions.

First of all, a note for readers who have never heard of $Increment. $Increment is a Caché ObjectScript function which performs an atomic operation to increment its argument by 1 and return the resulting value. You can only pass a global or local variable node as a parameter to $Increment, not an arbitrary expression. $Increment is heavily used when assigning sequential IDs. In such cases parameter of $Increment is usually a global node. $Increment guarantees that each process using it gets a unique ID.

a) Choose Add comment b) Write some text in comment (e.g. 'test') c) Click preview d) Edit comment content (e.g. 'test 2') d) Click preview again e) Notice that preview shows comment content before editing (e.g. 'test')

"Related conversations" section shows only comments number.

 In fact, these topics might also have answers.

For example, on next screenshot there are three topics in Related conversations section (on the right).

All three of them have answers, but they are shown as having 0 comments, thus seem as unanswered.

Please add possibility to sort posts on 'updated' field.

As I understand by default posts are shown not in order of last update.

Ability to view content by particular member is a great feature.

I'd like to propose some enhancements to this:

• Member content should be accessible from member page. For example, under separate tab.
• There should be possibility to follow member. For example, I want to be notified every time Evgeny Shvarov posts something.
• On member content page we should be able to filter by comments/posts/all content.

UPD: I found separate topic for first item of my list: https://community.intersystems.com/post/show-users-posts-user-page

Currently if I accidentally rate article as 4 I cannot change my vote.

Personally I'd prefer just +/- under the article.

There is thin line between 3 and 4 for the article or 2 and 1. Like/dislike is better in my opinion.

Please see attached screenshot

In "My Content" and "My Collaborations" headers for answers are shown with some internal Ids.

I think it should be just name of the corresponding question.

Hi.

It is easy to receive JSON representation or dynamic Array from %ListOfDataTypes:

set l=##class(%ListOfDataTypes).%New()
do l.Insert("a")
do l.Insert("b")
do l.Insert("c")

set arrStr=l.$toJSON()
zwrite arrStr
set arr=l.$compose([])
zwrite arr

How to make backward conversion? How to receive %ListOfDataTypes from dynamic Array an JSON string?

I've tried

SAMPLES>set list = ##class(%ListOfDataTypes).$fromJSON("[""a"",""b"",""c""]")

%FromObject+21^%Library.RegisteredObject.1 *%Exception.General Compose Compose %FromObject Unable to map from %Library.Array instance to %Library.

The object and relational data models of the Caché database support three types of indexes, which are standard, bitmap, and bitslice. In addition to these three native types, developers can declare their own custom types of indexes and use them in any classes since version 2013.1. For example, iFind text indexes use that mechanism.
